Abstract: A method of evaluating a person's olfactory perception by determining his ability to distinguish, differentiate, recognize, recall and remember distinct odors and scents when the person is presented with various odor-emitting samples. The odor-emitting samples are divided into several groups wherein the individual groups comprise two identical and one slightly different odor-emitting sample. Additionally, another group is presented to the person which comprises several individual odor-emitting samples which differ markedly from all of the other samples presented. The odor-emitting samples from the individual groups are presented to the person sequentially and the results are reported and then compared with other persons subject to the same tests. The person's olfactory perception acumen is thus recorded. This invention has great utility for many fast-growing and dynamic fields such as the food and beverage industry, academia and research facilities.
